, ALL VANGLE ROTARY MITE'RER t Louis Frederick Ross, Kansas City, Mo.Application June 2o, 1935,- serial No. 27,607 aoiaims. (c1. 144-134)This invention relates to a rotary mitering machine whichismainlydesignedfor cutting miters for framing borders for use insetting type forms in the printing industry.

The general objectgof the invention is provvide foot operatedfmeans forfeeding the work `to the cutting means so as to leave both hands of theoperator free-for handling the work on the cutting table and to make itpossible for vcutting the work at any desired angle including the oon-.ventional 45 degree angle.

.This-invention also consists incertain other Afeatures of constructionand in the combination and arrangement of several parts, to beVhereinafter fully desoribed, illustrated in theaccompanying drawingsand specifically pointed out ,in -the appended claims.

`In describing the invention in detail, reference will be hadtotheaccompanying drawings wherein like characters denote like orcorresponding parts. throughout the several views; and in 1 Figure 1Y isa, perspective frontview of the machine. l

Figure 5 is a. ure 2.

Figure 6 is a section on the line 6-6 of Figure 5.

Figure 7 is a section on the line 'I-'I of Figure 2.

Figure 8 is a view showing a supplemental memberV which might be used inplace of the tris-ection on the line 5-5 of Figangle.

In these drawings, the numeral I indicates a base and the numeral 2indicates a post rising from the base and having attached to its upperend a horizontal member 3 from which rise the bearing members 4 for theshaft 5. Tapered bushings are provided forY these bearings, one bushinghaving its small end exteriorly threaded to receive the nut 'I fortaking up wear in the bushing and the other bushing is engaged by a cap8 which surrounds a reduced externally threaded part 9 of the shaft 5,said shaft being adjusted to take up wear of the bushing through themeans of a nut IIJ threaded on the reduced l part 9, the nut being heldin place by the lock member I2 which is preferably of the spiraltype,

a hole I3 being formed in the shaft at the inner end of the'socket sothat a tool can be driven into the hole to'force the cutting member outof the socket. Grease cups I4 are provided on the bear- 5 ing members 4for supplying lubricant to the bushings and those parts of the shaftengaged thereby and a pulley I5 is attached to the shaft between thebearing members 4 for receiving a belt I6 which passes over a pulley I'Iattached 10 the shaft of a motor M which is attachedto the base I asshown in Figure 1.

A tubular member I8 is supported for vertical movement on the upper partof the post 2 and is formed with a bracket I9 which extends 15 outwardlyand upwardly and has a `horizontal part 20 at its upper end which isformed with the opening 2|. A block 22 having an opening-23 therein isseated on the horizontal part 2B and a segmental-shaped table 24 issupported on the 20 block 22 land this table has a bolt 25 passingtherethrough and said bolt 'passes throughthe openings 23 and 2| and isprovided with a thumb nut 26 on its lower end which bears against awasher 21 which engages the lower face of the 25 horizontal part 2D. Ascrew 28 is threaded into a hole in the front end of the block 22 andhas a groove thereinas shown at 29 Whichreceives -the forked end of thedepending part 30 ,of the table so that by loosening the nut 26 and then30 turning the screw 28 the table can be moved toward or away from thecutting member I2 which fits in the corner of the space formed by thepeculiar shape of the table, as shown in Figure 2.

Plates 3l are attached to the sides of the block 35 22 and dependtherefrom and the depending portions are provided with threaded holesfor receiving the screws 32 which engage the horizontal member 20, asshown in Figure 6. Thus by loosening the nut 26 and adjusting thesescrews 32 40 the block and the table 24 can be adjusted sidewise. i f

The top of the block 22 is formed with the keyways 33 which receive thekeys 34 of the underface of the table for preventing relative rotary 45movement of these parts while permitting the table to be adjusted on theblock toward and away from the cutting member. The keyways and keys alsocause the table to move with the .block when the block is adjusted bythe screws 32. Of course, after the table has been adjusted the nut 26is tightened to hold the parts in adjusted position.

The table is formed with a depending part 24' which carries the keys andthe parts 30 as shown 55 in Figure 4, this part being of rectangularshape and having a central opening 24" therein.

A foot pedal 36 is connected to one end of a shaft 31 journaled in abracket 38 on the base and an arm 39is connected to the other end of theshaft and a rod 48 has its lower end connected with the arm 39 and itsupper end to the bracket I9 as shown at 4I so that depression of thepedal will raisethe tubular part I8, the bracket I8 and the tableassembly.v `A bar 42 passes through a socket. "43 `carried by avertically arranged lug 44 on the upper part of the post and said bar isheld in adjusted position in the socket by a screw/45. l

The lower end of the'bar is adapted ,to engage a shoulder forming part46 on the'tubula-r parti-8 so as to limit upward movementl of the..tubular Y part I8 and the table assembly. Thus by adjusting the bar 42in the socketV `the'tablefcan be f stopped in its upward movement at anydesired point.
